Virtual LANs (VLAN) | 1059
Use the untagged command to move untagged interfaces from the Default VLAN to another VLAN:
The
no untagged interface command removes the untagged interface from a port-based VLAN and places
the interface in the Default VLAN. You cannot use the
no untagged interface command in the Default
VLAN. Figure 53-5 illustrates the steps and commands to move an untagged interface from the Default
VLAN to another VLAN.
Figure 53-5. Example of Moving an Untagged Interface to Another VLAN
The only way to remove an interface from the Default VLAN is to place the interface in Default mode by
entering the
no switchport command in the INTERFACE mode.
Step Command Syntax Command Mode Purpose
1
interface vlan vlan-id CONFIGURATION Access the INTERFACE VLAN mode of the VLAN
to which you want to assign the interface.
2
untagged interface INTERFACE Configure an interface as untagged.
This command is available only in VLAN interfaces.

Use the show vlan command to determine interface
status. Interface (gi 3/2) is untagged and in the
Default VLAN (vlan 1).
In a port-based VLAN (vlan 4), use the untagged
command to add the interface to that VLAN.
The show vlan command output displays the
interface’s changed status (gi 3/2). Since the Default
VLAN no longer contains any interfaces, it is listed as
inactive.
